Question

x-1/x=1/2 find 4x2+ 4/x2

Answer 1

Step-by-step explanation:

$\frac{x - 1}{x} = \frac{1}{2} \\ = > 2(x - 1) = > 1x \\ = > 2x - 2 = x \\ = > 2x - x = 2 \\ = > x = 2$

Now,

putting the value of x in the given equation,

$4 {x}^{2} + \frac{4}{ {x}^{2} } \\ = 4( {2}^{2} ) + \frac{4}{ {2}^{2} } \\ = 4 \times 4 + \frac{4}{4} \\ = 16 + 1 \\ = 17$
